PIR Sensor

<p><strong>Features: </strong></p>
<p>1. the automatic sensor: to enter the sensor output range is high, people leave the sensor range of the automatic<br />
delay off high, output low.<br />
2. the photosensitive control (optional, factory is not set) may be set the photosensitive control during the day or<br />
light intensity without induction.<br />
3. the temperature compensation (optional, the factory is not set): In the summer when the ambient temperature rises<br />
to 30 ~ 32°, a slightly shorter detection range, temperature compensation can be used as a performance compensation.<br />
4. two trigger modes: (can be selected by jumpers)<br />
a. can not repeat the trigger: the sensor output is high, the delay time is over, and the output will automatically<br />
become low from high;<br />
b. repeatable trigger: the sensor output is high after the delay period if the human body is in its sensing range<br />
activities, its output will remain high until after the delay and will be left high to low (sensor module review<br />
Measured activities of each body will be automatically extended after a delay time and the final event of<br />
the delay time Starting point of time).<br />
5. with induction blocking time (the default setting: 2.5S block time): sensor module, after each sensor output<br />
(high change Into a low level), you can set up a blockade followed by a period, in this period the sensor<br />
does not accept any sensor signal. This feature can have a"sensor output time" and"blocking time" The interval<br />
between the work produced can be applied to detect the interval Products; and also inhibit this function during load<br />
switching for a variety of interference. (This time can be set at zero seconds - Tens of seconds).<br />
6. the working voltage range: the default voltage is DC4.5V-20V.<br />
7. micro-power consumption: static current"50 microamps, especially for battery-powered automatic control products.<br />
8. the output high-level signals: types of circuits can be easily docked.</p>
<p><strong>Instructions: </strong></p>
<p>1. Sensing module for about a minute after power initialization time, during the interval to the output module<br />
0-3 times a minute in standby mode.<br />
2. Should avoid direct lighting such as interference sources close to the surface of the lens module to avoid the<br />
introduction of interference signal generator malfunction; use of the environment to avoid the flow of the wind, the<br />
wind sensor will also cause interference.<br />
3. Sensor module using a dual probe, the probe's window is rectangular, dual (A per B million) in the direction of<br />
the ends of the long when the body passed from left to right or right to left when they reach the dual IR time, distance<br />
the difference, greater the difference, the more sensitive the sensors, when the body from the front to the probe or from the top<br />
to bottom or from bottom to top direction passing, dual IR not detected changes in the distance, no difference value,<br />
the sensor is insensitive or does not work; so the sensors should be installed in dual direction of the probe with human<br />
activities as much as possible parallel to the direction of maximum to ensure that the body has been passed by the<br />
dual sensor probe. To increase the sensing range of angles, the module uses a circular lens, the probe also makes sense<br />
on all four sides, but is still higher than the upper and lower left and right direction of sensing range, sensitivity, and<br />
strength, still as far as possible by the above installation requirements.VCC, trig (control side), echo (receiving end), GND</p>
<p><strong>Dimensions and Adjustment: </strong></p>
<p>Note: The potentiometer is clockwise to adjust the distance, sensing range increases (about 7 meters), on the contrary,<br />
sensing range decreases (about 3 meters).Delay adjustment potentiometer clockwise rotation, sensor delay longer (about 300S),<br />
the other hand, induction by the short delay (about 5S).</p>
<p><strong>ApplicationsThe</strong></p>
<p>a. Security Products<br />
b. the human body sensors toys<br />
c. the human body sensor lighting<br />
d. industrial automation and control, etc.<br />
It can automatically and quickly open various types of incandescent, and fluorescent lamps, buzzers, automatic doors,<br />
electric fans, automatic washing machines and dryer Machines, and other devices, is a high-tech product. Especially<br />
suitable for enterprises, hotels, shopping malls, warehouses family aisles, corridors, and other sensitive<br />
Sense of region, or for the security zone automatic lighting, lighting, and alarm systems.</p>
